Here's how it works: Anybody can ask a question The best answers are voted up and rise to the top This patent application US20130047644 A1 refers to using Vetiver grass roots for cooling screens. Seems strange to attempt to patent this use as Vetiver roots have been used for this purpose for millennia in India, and the knowledge has been in the public domain for centuries. According to the Wikipedia page for the plant, there is a reference to cooling uses in the book CRC Handbook of alternative cash crops published in 1993. I do not own this book, so I can not personally verify the claim.

Using mats made of "khus"/ Vetiver grass is used extensively in India during the summer months. These mats of the roots of the "Khus" plant are bound in wooden box frames with a fan inside which blows cool air after the mats are made wet with water dripping from the top. The plant is also used for making a cooling drink sold commonly across India Here is an abstract from a write up on the railways system in British India, circa 1911. The first and second classes are invariably supplied with bathrooms, so that the traveller can enjoy the luxury of the tub. The water which is carried on the roof is replenished frequently at the larger stations. In summer the windows are fitted with rotating fans, that force moist, cooled air through dripping khus khus (a species of tall grass) mats. These luxuries are a necessity in the burning sun of the Indian plains. Another refernce is from the Gazette This patent is specious and illegal. Khus roots for cooling have been used for more than a century in India and Pakistan.

Using Vetiver /khus roots for cooling screens and cooling blinds/thick curtain is very very old tradition in India. One can find households using it still. In Madhya Pradesh and UttarPradesh in India so many manufacturers still make this curtains for domestic use as well as export. In fact the people applied for patent must be of Indian origin. Because for such knowledge we have local phrase in Hindi "yeh to bacha bacha janta hai" Means "each and every child knows it." As for its references, one can find it in any Sanskrit writings including centuries old Ayurved, Charaksahinta and other literature. It has been in extensive use by East India company before independence of India 1947,tribal people hand made cooling curtains and cooling pads were used for several years in Desert coolers, as it is locally called, from wild indigenous Vetiver root. After colonial raj,independent India had this cooling curtains in all the government offices located in in Nagpur and Chandrapur in Maharashtra State.

In fact 2 months of extreme summer i.e April and may every year Cetral Government of India had special budgetary provision in these district offices, for watering personnel's special allowances.

Also known as vetivert, khus, or khus khus, Vetiver has a long history of use and is very well known as the Oil of Tranquility.1 It is obtained from the roots of a tropical grass originally from India and Sri Lanka, but the plant is now grown in many tropical countries. From time immemorial, one of the oldest aromatic uses of vetiver roots is to weave them into mats which, when dampened with water and hung in windows like curtains, cool and scent the air with a pleasant aroma.2 Vetiver oil is thick and, like Patchouli and Sandalwood, improves with age; it is a premium base note and makes an excellent fixative in essential oil formulas. It is used in formulas for arthritis and muscular aches as well as for its sedative, relaxing qualities. It helps stimulate circulation, is good for acne and oily skin, and helps to relieve nervousness while promoting tranquility.

Vetiver is also a good grounding oil for those who focus on intellectual activities to the exclusion of the physical, to add to the bath for an exceptional stress-relieving soak, and to use in the case of shock due to, for example, an accident, lost of employment, bereavement, separation, or divorce.3,4,5,6 Aromatic Profile: Deep, slightly sweet and resinous, with pronounced earth and root notes and light smoky undertones; an excellent fixative and base note that has about the same depth as our Double-Distilled Vetiver.
